摘要
传统观念认为，在单夯夯击能２０００ｋＮ·ｍ情况下，强夯法仅对浅部地基土层具有加固作用，而对深部土层却没有加固作用。通过浦东机场强夯地基与天然地基沉降观测资料的对比分析，认为：强夯不仅可加固浅部土层，而且也可加固深部（１０ｍ以下）的饱和软土，有效加固深度可达２０ｍ左右。
The traditional view is that only the shallow soil layers can be reinforced and the deeper layers can not be reinforced during dynamic consolidation in the condition of 2000 kN·m of a-tamp-energy.By comparing the monitoring settlement data of the tamped foundation to with that of natural foundation at Pudong Airport, a new conclusion is drawn in this paper that dynamic consolidation can reinforce not only the shallow hard soil , but also the deeper (below 10 meters) saturated soft clay. The effective consolidation depth is about 20 meters.
